RICHARD R. MOFFATT, OF BROOKLYN, NEW YORK.

Letters Patent No. 110,383, dated December 20, 1870.

IMPROVEMENT lN SHOT-CARTRIDGES.

The Schedule referred to in these Letters Patent and making part of theSame.

Be it known that I, RICHARD It. MoFFA'rT, of the city of Brooklyn,county ot' Kings and State of New York, have invented a new and usefulImprovement in Shot-Gases for Cartridges, Svc., of which the followingis a specification, reference being had tothe accompanying drawing.

lhe object of my invention is to provide a shotcase or envelope whichhas the advantage of protecting the bore of the gni from leading, usualto shotczlses, and to avoid the defects in practice found to exist inclosed cases or envelopes now in use, which are that frequently the shotis held within said case during its ight, and thereby fail to attain theobject desired.

It consists in a novel method of constructing the case or shell thatenvelops the shot by treating it with a compound which will make itwholly or partly consumable whcn'tired from the gun, thus freeing theshot and ena-bling them to spread or scat-ter.

-In the accompanying drawing- Figure 1 represents a central section of ashot-case embodying my invention.

Figure 2 represents an elevation View of the shotcase and cartridgeattached.

Similar letters of reference in the figures indicate like parts.

In the drawing- Letter A is the case or shell, which is made of' paper,paper-pulp, or any other fibrous material. This is shaped into anydesirable form and intended to envelop the charge of shot.

B is a wad which closes the open end or 'base of the shell A after theshot has been placed therein. rlhis shell or case A, and also the wad B,if desired, may be made wholly or part-ly consumable, but I pret'cr tomake only the forward end of the caseA consumable. This is done bytreating the paper or other fibrous material which composes the case orshell with a solution of niter and water, or by means of nitric andsulphuric acid, or by oxidized carbvolic acid, or by any other knownmethod which m'ay'produce the desired effect, and it may be appliedbefore or after thc shell or case A is formed. A

The case or shell-A, when complete, is inserted or partly inserted inthe cnd ot' a metallic or paper. shell ot' a cartridge, as shown in fig.2, or, if desired, it may be used with loose powder in muzzle-loadingguns.

In the formation of my shell or case it may be made ot' pulp, whichisprepared with the combustible compound beforc it is formed into shape toreceive the shot.

Having thus described my invention,

I desire to secure by Letters Patent- A shot-case or shell made partlyor wholly consumable, 'substantially as and for the purpose herein setforth.

R. R. MOFFAT'I.
